Add Director Biography
Director Statement

The original concept of Cortisol was to make a film about wilderness and the fear of being stalked by an unseen foe. Set where I grew up, in the vast open countryside of Norfolk, it followed a man obsessed with the idea of finding a big cat that was said to haunt the open fields and woodlands. We follow his journey to corner his prey. With that simple concept I then layered on a background of ancient myth and legend.
In Norfolk you are surrounded by evidence of the long dead, crumbling monasteries, ruined castles, ancient earth works and the sites of forgotten settlements. The air of the Anglo-Saxon and Celtic realms still live and breathe in the fields and silent woodlands. Deep in these bastions of nature it’s easy to still believe in something else.
Fast forward several years and I had moved to London. Through my work as a videographer I worked for a charity helping to document inner city social schemes. I found myself in some of the toughest estates in London and remembered the story from back home, then merged the two. The journey remains (this time involving the search for his missing brother), as does the obsession, but now the story is set in the haunted canyon of a crumbling housing estate, cut off from the world, constantly in fear of the encroaching wilderness. In this isolated world James finds that if you look long enough into the abyss, the abyss will look back into you. Beware the shadows...
